01
Culex tarsalis
A banded leg Culex mosquito associated with West Nile virus surveillance and western or plains habitats.
Oklahoma mosquito identification and health risk center
More than an outdoor nuisance.
Not every mosquito carries a disease. Species, local surveillance, exposure, and public health guidance determine the health context. Property management starts with water, shelter, and activity patterns.
Risk communication ruleEvidence first. Medical diagnosis belongs with a qualified clinician.
Identification
Read the body. Then find the water.
Mosquitoes differ in markings, activity time, preferred hosts, and breeding sites. A close specimen or clear photograph can help, but site conditions and local surveillance add essential context.
02
Southern house mosquito
Culex quinquefasciatus often uses nutrient rich standing water around structures and is most active from dusk through night.
03
Asian tiger mosquito
Aedes albopictus has bold black and white markings and can use small water holding containers near homes.
Health context
Keep the risk specific.
Oklahoma guidance includes West Nile virus, St. Louis encephalitis virus, La Crosse virus, and Jamestown Canyon virus among mosquito borne disease concerns. Most mosquito bites do not cause disease.
West Nile virus
Most infected people do not develop symptoms. Some develop febrile illness, and a smaller number develop severe central nervous system disease.
Who faces higher West Nile risk?
Risk of severe disease increases with age. Certain chronic conditions and weakened immune systems may also increase risk.
La Crosse virus
Most infections are not apparent. Neuroinvasive disease occurs most often in children under 16.
Other Oklahoma concerns
St. Louis encephalitis and Jamestown Canyon virus appear in Oklahoma public health guidance. A clinician evaluates illness and individual risk.
Property guidance
Practical prevention
Use the property evidence, environmental conditions, and professional guidance to decide the next step.
Practical prevention01 02 03 04
Tip and drain
Empty, remove, cover, or maintain water holding containers around the property.
Maintain the envelope
Repair window and door screens and reduce openings that allow mosquito entry.
Use public health guidance
Follow EPA label directions for repellents and local public health recommendations.
Protect animals responsibly
Ask a veterinarian about animal specific risk, symptoms, and preventive decisions.

Mosquitoes concerns
Reduce breeding habitat and outdoor pressure.
We identify breeding areas, resting zones, and environmental conditions contributing to mosquito activity, then design a treatment and prevention plan for the property.
